Backdoor.Multi.ZAccess.gen infection

I have been hearing commercials/ads on my computer for the last few days while also experiencing redirects on my explorer page or just random windows opening with sites to advertisements or just google. I've done a tdss killer scan and it came up with only one infection: Backdoor.Multi.ZAccess.gen. I was now under the impression that if I got rid of this it would end the problems with my computer. I've tried deleting it but end up having to use a system restore because I find my computer in a constant reboot cycle. I would greatly appreciate guidance to rid my computer of all of these problems. Thank you.

My name is Gringo and I'll be glad to help you with your computer problems.

I have put together somethings for you to keep in mind while I am helping you to make things go easier and faster for both of us

Please do not run any tools unless instructed to do so.

We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability.

Please do not attach logs or use code boxes, just copy and paste the text.

Due to the high volume of logs we receive it helps to receive everything in the same format, and code boxes make the logs very difficult to read. Also, attachments require us to download and open the reports when it is easier to just read the reports in your post.

Please read every post completely before doing anything.

Pay special attention to the NOTE: lines, these entries identify an individual issue or important step in the cleanup process.

Please provide feedback about your experience as we go.

A short statement describing how the computer is working helps us understand where to go next, for example: I am still getting redirected, the computer is running normally, etc. Please do not describe the computer as "the same", this requires the extra step of looking back at your previous post.

NOTE: At the top of your post, click on the Watch Topic Button, select Immediate Notification, and click on Proceed. This will send you an e-mail as soon as I reply to your topic, allowing us to resolve the issue faster.

NOTE: Backup any files that cannot be replaced. Removing malware can be unpredictable and this step can save a lot of hartaches if things don't go as planed. You can put them on a CD/DVD, external drive or a pen drive, anywhere except on the computer.

NOTE: It is good practice to copy and paste the instructions into notepad and print them in case it is necessary for you to go offline during the cleanup process. To open notepad, navigate to Start Menu > All Programs > Accessories > Notepad. Please remember to copy the entire post so you do not miss any instructions.

Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.

A Notepad document should open automatically called checkup.txt; please post the contents of that document.

Run Combofix:

You may be asked to install or update the Recovery Console(Win XP Only) if this happens please allow it to do so (you will need to be connected to the internet for this)
